Childlessness is becoming more common in the United States. A Pew Research Center study found that 18 percent of women aged 40 to 44 have never had children, compared to 10 percent in 1976. Pew's researchers said the trend is a result of a combination of less social pressure to have children and women delaying marriage to later in life, when the ability to become pregnant has declined. Changing attitudes about the purpose of marriage also seem to be playing a role: A 2007 Pew study found that 41 percent of adults said having children is very important for a successful marriage, down from 65 percent in 1990.
